Introduce a testbed for merging multiple ASTs into a single AST context with the AST importer. WIP, still useless but at least it has a test. llvm-svn: 95683 2010-02-10 03:21:46 +08:00			`// RUN: %clang_cc1 -emit-pch -o %t.1.ast %S/Inputs/var1.c`

Hook up the diagnostics-argument printer when merging AST files, so that we get readable diagnostics such as: error: external variable 'x1' declared with incompatible types in different translation units ('double ' vs. 'float *') However, there is no translation of source locations, yet. llvm-svn: 95704 2010-02-10 06:37:58 +08:00			`// CHECK: error: external variable 'x1' declared with incompatible types in different translation units ('double ' vs. 'float *')`
